Title: Production of fired dust pellet
Inventor: HAITANI MASAHIKO
IPC: B09B3/00
Filed: 1978-05-24
Abstract: PURPOSE: Dust containing harmful material such as mercury is grained and fired thereby providing in an inexpensive mass production manner fired dust pellets which are not sprayable in transport and not dissolved in reclamation word and ocean disposal.  
     CONSTITUTION: Dust discharged from cast iron or steel making process is collected by the dust collector and the dust containing harmful material such as mercury is grained using grainer. Or, the dust is premixed with 10% of glass powder and then grained. The resulted grain is fired at 900 to 1000°C for glass-less dust grain, and at temperatures 200°C below than the above for 10% glass containing dust grain. This firing causes harmful Hg to evaporate and disappear, and other harmful material to decrease to the value below the ideal target for preventing public pollution by material dissolution. The firing further lowers the pellet pH to a degree less than public pollution.
